摘　　要：报道了弯弓蚌螨在宿主三角帆蚌上的空间分布型。利用扩散性指标(Iδ),方差(V)与均值(X)的比大于1;Taylor幂函数法则lgV=lg9.954+1.227lgX,Iwao平均拥挤度(X )和平均密度(X)间的关系X =3.862+2.142X等方法,结果表明:弯弓蚌螨在宿主三角帆蚌中的分布为聚集型。The article reported some population parasitic relationship between the Unionicola arcuata and Hriopsis cumingii.The index of aggregation (variance and mean density,mean crowding and mean density) are more than one,the equation of Taylor and Iwo are lgV=lg9.954+1.227 lgX and X*=3.862+2.142X respectively.The statistical results showed that the distribution of U arcuata in H cumingii was aggregation pattem.
